I’m using Brave with 3 differents device but with 3 different BAT balance. 1 for my personal computer, 1 for my working computer and 1 with my smartphone.
Is it possible to synchronize all these device to have one single BAT balance?
Yes, settings then sync. You may need to Enable sync first as I don’t think it was default included on the most recent versions. So I would probably check to see first if there was a reason it was disabled (in case you lose so of the BAT or something). Sorry, not much use, eh?!
